I've had this problem for 2 days now also! Usually I'm on ign or YouTube & to quit I would use PS menu button, select app in menu & I would then close it. The options are all gone! Only delete app option shows. So what I have been doing is if I'm on YouTube, I just select ign app to automatically switch over. Something's up! I've never tried to rebuild the database. I'm not even sure where option is lol. Also noticed on YouTube that the triangle button no longer acts as space when typing search
